Californians enrolled in Covered California will see premiums rise by an average of 12.5 percent next year, according to rates released Tuesday.

"Anthem Blue Cross of California will be returning in just three of Covered California's regions," Lee announced Tuesday in a teleconference with reporters.

Lee says Anthem will continue in the northern Counties, Santa Clara and the Central Valley. That means 150,000 Californians will need to find a new plan for 2018.

Insurers across the nation face uncertainty as to how the U.S. health care system will evolve. One big unkown is whether the White House and Congress will subsidize out-of-pocket costs for low-income consumers.
